f2fs: introduce -o fastboot for reducing booting time only · d5053a34

由 Jaegeuk Kim 提交于 10月 30, 2014

If a system wants to reduce the booting time as a top priority, now we can
use a mount option, -o fastboot.
With this option, f2fs conducts a little bit slow write_checkpoint, but
it can avoid the node page reads during the next mount time.

f2fs: avoid race condition in handling wait_io · 6a8f8ca5

                       wait_io = X              wait_io = x

                                                 kernel panic

In order to avoid this, this patch removes the wait_io facility.
Instead, we can use wait_on_all_pages_writeback(sbi) to wait for end_ios.

f2fs: send discard commands in larger extent · adf4983b

由 Jaegeuk Kim 提交于 10月 28, 2014

If there is a chance to make a huge sized discard command, we don't need
to split it out, since each blkdev_issue_discard should wait one at a
time.

f2fs: revisit inline_data to avoid data races and potential bugs · b3d208f9

由 Jaegeuk Kim 提交于 10月 23, 2014

This patch simplifies the inline_data usage with the following rule.
1. inline_data is set during the file creation.
2. If new data is requested to be written ranges out of inline_data,
 f2fs converts that inode permanently.
3. There is no cases which converts non-inline_data inode to inline_data.
4. The inline_data flag should be changed under inode page lock.

f2fs: fix possible data corruption in f2fs_write_begin() · 9234f319

由 Jan Kara 提交于 10月 22, 2014

f2fs_write_begin() doesn't initialize the 'dn' variable if the inode has
inline data. However it uses its contents to decide whether it should
just zero out the page or load data to it. Thus if we are unlucky we can
zero out page contents instead of loading inline data into a page.
